It's the comedy that's the best sell for the game. And the improved models over the course of the games he's made. The first one had good ones but this one had way better. And in terms of comedy it's meta without fully breaking 4th wall. For example, a running theme in erotic games is that women will obsess over huge penises and freeze in their tracks. This happens a lot in this and his earlier game. And tons more. Since that's a huge gimmick, they even turned it into a joke in this game. When there's a serious moment where everyone needs to focus and do their job, the one monkey wrench in the plan is a girl ignoring all life threatening events because a huge penis is near her. Satire like that touches on two level. A jab at ero VNs in general, and a jab at the running gag in Caribdis' games. Plus it is even more of a heckle of spaz characters like "manick pixie dream girls" who can sometimes be too quirky for their own good.
